Description

Technical fields:

[0001] This utility model relates to the technical field of forging conveyor lines, and more specifically to a sorting device for the head and tail cutting sections of bar stock. Background technology:

[0002] Currently, the main processing methods for bearing rings are forging and machining. Forging is the process of machining the ring from a cylindrical bar into a ring blank. The first step in forging is to heat the long bar and then cut it into short bars. These short bars are then hot-forged into ring blanks. Before hot forging, the processing of these short bars is particularly critical, as it not only affects the performance of the ring blank itself but also the forging production. For example, the problem of stack forging can occur. Stack forging refers to forging two short bars together, mainly due to temperature issues with the bars. The previous short bar may not have fully detached from the forging die before the next short bar is forged. If the bar stock enters the forging mold again, it will cause damage to the forging mold; therefore, the temperature of the bar stock needs to be strictly monitored. Currently, the main method is to cut off both ends of the long bar stock on the cutting forging line. However, the problem of overlapping forging will occur in the subsequent forging process. Therefore, it is proposed to manually sort out the first and last ten segments of the bar stock. After manual inspection, qualified segments are put into subsequent forging, which can effectively improve the overlapping forging situation. However, manual sorting is troublesome. Therefore, it is proposed to use the bar stock counting function on the cutting forging line to know the first and last ten segments of the long bar stock. It is necessary to design a structure to sort out the first and last ten segments. Utility model content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a sorting device for the head and tail cutting sections of bar stock.

The lower end of the valve plate is close to the side plate of the sorting chute and is hinged to the sorting chute through a hinge shaft. A control arm is formed on the valve plate. The control arm is located at the upper part of the sorting chute and is connected to the piston rod of the sorting cylinder. The sorting cylinder drives the valve plate to rotate around the hinge shaft to realize the opening and closing of the sorting outlet.

[0017] Example: See Figures 1 to 3As shown in the figure, a sorting device for the head and tail cutting sections of bar materials includes a bar cutting and conveying line 1. Below the outlet of the bar cutting and conveying line 1, there is an inclined sorting chute 3. Below the sorting chute 3, there is an inclined bridging belt 2. Sorting outlets 31 are formed on the side plates on both sides of the sorting chute 3. Diagonal chutes 4 connected to the sorting outlets 31 are fixedly connected to both sides of the sorting chute 3. A hopper 41 is formed at the lower end of the diagonal chute 4.

[0018] A "person" - shaped conversion door is arranged in the sorting chute 3 between the sorting outlets 31. The conversion door is composed of two groups of symmetrically arranged valve plates 5. The lower end of the valve plate 5 is close to the side plate of the sorting chute 3 and is hinged to the sorting chute 3 through a hinge shaft. The hinge shaft is inserted into the valve plate 5, and the lower end of the hinge shaft extends out of the valve plate 5 and is inserted and fixed to the valve plate 5.

[0019] A control arm 51 is formed on the valve plate 5. The control arm 51 is located on the lower side of the valve plate 5. The control arm 51 is located in the upper part of the sorting chute 3 and is connected to the piston rod of a sorting cylinder 6. The sorting cylinder 6 drives the valve plate 5 to rotate around the hinge shaft to open and close the sorting outlet 31.

[0020] There are two groups of the sorting cylinders 6, which are respectively arranged on both sides of the sorting chute 3. A cross - support beam 7 is fixedly connected to the cylinder body of the sorting cylinder 6, and the cross - support beam 7 is fixedly connected to the sorting chute 3.

[0021] A fish - eye joint is screwed and fixed on the piston rod of the sorting cylinder 6. A guiding pin shaft is pivotally connected to the fish - eye joint. A guiding groove is formed on the control arm 51, and the guiding pin shaft is inserted into the guiding groove of the control arm 51.

[0022] The control arm 51 is located on the upper side of the valve plate 5. The width of the guiding groove on the control arm 51 is equal to the diameter of the guiding pin shaft, and the guiding pin shaft is T - shaped.

[0023] The included angle between the control arm 51 and the valve plate 5 is an obtuse angle. The lower end of the valve plate 5 is located below the sorting outlet 31 on the sorting chute 3, and the length of the valve plate 5 is greater than the length of the sorting outlet 31.

[0024] The width of the bar cutting and conveying line 1 is not greater than the width of the sorting chute 3, and the width of the sorting chute 3 is less than the width of the bridging belt 2.

[0025] Working principle: This solution is a sorting device for the head and tail cutting sections of bar materials. The sorting device can cooperate with the counting function of the bar cutting and conveying line to sort out the ten sections at the head and tail of the long bar from the forging feeding line.

[0026] The main function of this device is to separate the beginning and end sections of long bars for output. On the bar cutting conveyor line, a temperature sensor first detects the hopper and end of the long bar. Based on the signals from the hopper and end, the piston rod of the sorting cylinder 6 extends, causing the valve plate 5 within the sorting chute 3 to rotate, forming a V-shaped switching gate. Figure 3 As shown, after the material sections produced before and after the material head and material tail enter the sorting chute 3, they enter the inclined material channel 4 based on the guidance of the conversion door, and finally enter the hopper 41. Then, the hopper 41 is fully inspected.

[0027] After excluding the first and last ten segments of the long bar, the switching gate is switched, and the valve plate 5 rotates to close the entrance of the inclined material channel 4, so that the product slides down the sorting chute 3.
